Ibn Abi Arubah (may Allah have mercy on him) narrates from Qatadah (may Allah have mercy on him) that the Messenger of Allah (peace and blessings be upon him) was in the house of Sayyidah Hafsah (may Allah be pleased with her). When Sayyidah Hafsah (may Allah be pleased with her) came in, she saw the slave-woman with him (peace and blessings be upon him). She said: "In my house and on my day?" He (peace and blessings be upon him) said: "Be quiet. By Allah, I will not go near her; she is forbidden to me."
